The invention provides a method of reducing or preventing mitochondrial permeability transitioning. The method comprises administering an effective amount of an aromatic-cationic peptide having at least one net positive charge; a minimum of four amino acids; a maximum of about twenty amino acids; a relationship between the minimum number of net positive charges (p.sub.m) and the total number of amino acid residues (r) wherein 3p.sub.m is the largest number that is less than or equal to r+1; and a relationship between the minimum number of aromatic groups (a) and the total number of net positive charges (p.sub.t) wherein 2 a is the largest number that is less than or equal to p.sub.t+1, except that when a is 1, p.sub.t may also be 1.

The invention relates to a sustained release biodegradable ocular implant containing a tyrosine kinase inhibitor dispersed in a hydrogel for the treatment of a retinal disease for an extended period of time.

The disclosure provides methods of preventing, ameliorating or treating disruption of mitochondrial function and symptoms thereof. The methods provide administering aromatic-cationic peptides in effective amounts to prevent, treat or ameliorate the disruption of mitochondrial oxidative phosphorylation in a cell such as that found in a subject suffering from, or predisposed to a mitochondrial disease or disorder. In some embodiments, the methods comprise administering to a subject suffering from, or at risk for a mitochondrial disease or disorder, an effective amount of an aromatic-cationic peptide to subjects in need thereof.

The present invention provides peptide compounds that regulate the complement system and methods of using these compounds. The invention is an isolated, purified peptide of 30 amino acids derived from human astrovirus protein, called CP1. The invention is directed to peptide compounds that are peptide mimetics, peptide analogs and/or synthetic derivatives of CP1 having, for example, internal peptide deletions and substitutions, deletions and substitutions at the N-terminus and C-terminus, and that are able to regulate complement activation. The invention further provides pharmaceutical compositions of therapeutically effective amounts of the peptide compounds and a pharmaceutically acceptable carrier, diluent, or excipient for treating a disease or condition associated with complement-mediated tissue damage.

Peptides are provided consisting of L- and/or D-amino acids and combinations thereof, which affect myeloid cells by action on the triggering receptors expressed on myeloid cells (TREMs), including TREM-1 and TREM-2. The peptides act on the TREM/DAP-12 signaling complex. Also provided are lipid and sugar conjugated peptides comprising L- or D-amino acids. A method is provided of designing the peptides and lipid- and/or sugar-conjugated peptides comprising L- or D-amino acids. The disclosure relates to the therapy of various myeloid cell-related disease states involving the use of these peptides and compounds. The peptides and compounds are useful in the treatment and/or prevention of a disease or condition where myeloid cells are involved or recruited. The peptides of the present invention also are useful in the production of medical devices comprising peptide matrices (for example, medical implants and implantable devices).
